Answer:

≈ 11.78 in

Step-by-step explanation:

The arc length is calculated as

arc = circumference of circle × fraction of circle

= 2πr × $\frac{\frac{\pi }{4} }{2\pi }$ ( cancel 2π on numerator/ denominator )

= 15 × $\frac{\pi }{4}$

= $\frac{15\pi }{4}$

≈ 11.78 in ( to 2 dec. places )

Answer:

Account 1 yields greater return.

Step-by-step explanation:

Lets solve for the first formula:

$A=P(1+\frac{r}{n} )^{nt}$

First, change 6.5% into a decimal:

6.5% -> $\frac{6.5}{100}$ -> 0.065

Now, plug in the values for Account 1:

$A=3,000(1+\frac{0.065}{2})^{2(10)}$

$A=5,687.51$

<u>Now solve for Account 2:</u>

Change 6% into a decimal:

6% -> $\frac{6}{100}$ -> 0.06

Now plug in the values:

$A=3,000e^{0.06(10)}$

$A=5,466.36$

Account 1 yields better money after 10 years.

You weld two piece's of steel together. The toral thickness is 33/64 inch. If one piece of steel is 9/32 inch thick, how thick t

Anon25 [30]

Subtract the thickness of the known piece from the total thickness.

Because they have different denominators rewrite them to have the same.

9/32 x 2 = 18/64

Now you have 33/64 - 18/64 = 15/64

The other piece is 15/64 inch thick.
